Title: Rotary compressor blade
Inventor: KOMINE KENJI
IPC: F04C18/356
Filed: 1982-06-28
Abstract: PURPOSE:To make a rotary compressor lightweight and improve the strength and molding workability by molding a vane dividing a cylinder chamber into a suction chamber and a compression chamber with a reinforced plastic material and by filling hollow spherical grains in it. CONSTITUTION:A vane 5 is molded in a plate shape using plastics as a base material 13, and hollow spherical grains 16 are arranged and filled in it at random as a reinforcing material. The hollow spherical grain 16, made of a hard glass material, etc., is lightweight and has high strength, and is also molded with a material highly adhesive to the base material 13. Since the hollow spherical grain 16 is spherical in its outer shape, a force acting on the boundary surface 17 with the base material 13 is totally broken down into a force in the normal direction and a force in the tangential direction and is dispersed in each direction, thereby local concentration of stress is prevented from occurring.

Title: Grain-oriented silicon steel sheet and tensionincreasing method of grain-oriented silicon steel sheet coating film
Inventor: MURAKAMI KENICHI
IPC: C23C22/00
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To increase the tension imparting effect of a tension addition type insulating film formed on the surface of a steel sheet having no forsterite coating film by applying a coating solution consisting essentially of boric acid and boehmite, continuously annealing to form a coating film and annealing at a specific temp. for a specific time. SOLUTION: The annealing is applied at 500-1000 deg.C for >=0.5 hr. The composition ratio of boric acid to boehmite is preferably 0.2<=B2 O3 /Al2 O3 <=1.0 respectively expressed in terms of oxide by mol. And the annealing after the formation of coating film is preferably carried out after an iron core is formed. The difference of the coefficient of thermal expansion between aluminum borate generated by the reaction of boric acid with boehmite and the steel sheet causes the insulating film to impart tension to the steel sheet. In the continuous annealing, the reaction of boric acid with boehmite is insufficient in the insulating film because of the short annealing time and then, the tension imparting effect is increased by applying batch annealing for a long time to carry out the reaction to generate aluminum borate.

IPC: B41J2/055
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an ink injection device for satisfactorily forming a dense image by injecting a plurality of ink droplets. SOLUTION: In the case of forming a dense image by injecting two droplets of ink according to one print command of one dot, when the droplets 99 are integrated until it arrives at a recording medium 97, most 99a is absorbed to the medium 97, and hence size of the droplets 99 as seen from a surface of the medium 97 is not so changed from the case that only one droplet is injected (AB). Integration of the droplets 99 is prevented until it arrives at the medium 97, while the ink injection device and the medium are relatively moved so that two droplets 99 are partly superposed on the medium 97 (C, D). This operation can be realized by suitably setting a driving timing of an actuator for changing the volume of the chamber, fore example, by a piezoelectric material in the device having the actuator.

Abstract: PURPOSE:To prevent the curling of sheets of paper in a paper feeding cassette by installing a paper curl retainer formed with a thin board material having elasticity on a fixed part for mounting a paper feeding cassette, in such a way that it is lightly brought into pressure contact with the front part of sheets of paper housed in the paper feeding cassette at the time of mounting the paper feeding cassette. CONSTITUTION:A paper curl retainer 362 has inclined parts 362a on both ends of its front part to prevent the breakage of the retainer itself and the shifting of the top end side of a sheet of paper at the time of mounting/removing a cassette 300, while its stiffness is made a required minimum to suppress the curling of sheets of paper. Hence, in this option tray 9, even if both side parts of sheets of paper 301 which are fully loaded in the cassette 300 are being curled, the curling of the topmost sheet of paper 301 is suppressed with a stiffness to such an extent that it does not affect the paper feeding of a feed roller 302 by means of the paper curl retainer 362. Thereby, it can be prevented that a curled sheet of paper 301 which is brought into contact with the roller 302 is turned up while preventing a jam caused by curling at the time of conveying, and the like.

IPC: H03M5/04
Filed: 1979-09-05
Abstract: PURPOSE:To perform normal demodulation under no influence of a change in tape speed due to disturbance by integrating a digital signal having pulse width modulated by use of a counter that can count up and down. CONSTITUTION:Pulse-width-modulated digital signal (a) is inputted to increase- decrease control terminal 9 of counter 6 and also to rise detecting circuit 5, the output pulse of which is applied to reset terminal 10. Counter 6, reset to initial value (n) when signal (a) is inputted, counts up in the pulse-width t7 period extending over one pulse cycle of data [0] and counts down to the contrary in the remaining period t8 up to a point right before arrival of the next data [1]. Therefore, the count value, the output of counter 6, is less than reference (initial) value (n) in the end of data [0] and no pulse is outputted from comparator 8. Consequently, holding circuit 4 can output an invariably normal demodulated signal without being influenced by disturbance.
